3: Trapped

"Well, that was easy," you think to yourself as you and Joe burst into SF3201. Much to your surprise, you see Bob in the corner, gagged and bound. "Bob!" you both cry, running to his side.

The door slams shut. A lock clicks. You hear a voice from the other side. "Don't worry, you won't be in there for long," Chief Herrington says. "I knew I shouldn't have trusted this loser to keep a secret. I'm off to put the Cannon somewhere safe - I'm not trusting anyone but myself from now on." His laughter echoes as he walks down the empty hallway.

"We're trapped!" Joe wails, banging his fists against the locked door.

"Calm down," you tell him, staring at the complicated knots around Bob's wrists and ankles. "Let's try to untie Bob first."

Hint: Some assembly required. Think in layers. Have you seen anything like this before?
